| Abstract/Contents: | Five major factors determine the adaptability of a turfgrass irrigation system to soil climatic conditions. 1. Amount of water applied--Application rates depend on drought tolerance of the grass, root depths, and soil texture. Extra watering can control salt levels, but excessive irrigation results in leaching of nutrients and a waterlogged soil. Estimates to refill water levels in soils are based on evaporation rates, area to be irrigated, soil depths, and discharge rate of sprinklers. 2. Rate of application--Rates should not be faster than the rate at which water will enter soil. Topography, soil texture, thatch, and compaction are the major factors influencing rates. A regular aerifying program reduced thatch and compaction problems. 3. Frequency of applications--Condition of the grass and soils determine irrigation frequencies. Indicators of a drought stressed turf are: wilting, crumbly soil in a soil probe, localized dry spots, high temperature and winds and low soil moisture matric potentials. 4. Uniformity of application--To determine uniformity, place 3 or 4 cans at varying distances from the sprinkler. If variations are greater than 25%, improvements of uniformity are needed. 5. Quality of irrigation water--The most important criteria from a chemical analysis of water are: concentration of soluble salts and its proportion to calcium and magnesium, concentration of bicarbonates, and concentrations of toxic elements (boron, lithium, chlorine). |
